PATENT oFFicE f UNITED STATES CLARK E. RANNEY, OF TULSA, OKLAHOMA.

DERRICK.

Application filed August 9, 1926.

a simple and inexpensive form of bracket which possesses su'flicient strength and rigidity to Withstand the strains to which the bracket is placed.

In the drawings Figure 1 represents a view of a corner post with the attached girths; and,

Figure 2 is a detailed View of the bracket parts.

Referring now more particularly to the drawings, wherein like reference characters indicate corresponding parts, the numeral 1 designates the corner leg or post of a derrick. This is usually a rectangular Wooden beam, although it can be constructed of other In oil derricks there are usually four of these legs connected together by girths and trusses. This invention relates particularly to a bracket structure for connecting the girths to the corner leg. As

shown in Figure 1, girths 2 and 3 are secured to the corner post 1, these girths extending at right angles to each other. To support these girths, apair of irons t and 5 are provided. Each iron. comprises a sin gle strip of metal bent to form the angle shaped parts as clearly shown in Figure 2. These inside irons are perforated to receive fastening bolts by means of which they are attached to the girths and the corner leg.

Serial 'No. 128,238.

The girths rest on said irons, one iron supporting each girth.

A metallic plate 6 is also provided, which is of a substantially L-shaped structure having one arm 7 thereof overlying the bracket 4:, While the other arm 8 overlies the bracket or iron 5. These arms 7 and 8 are connected by an integral web and as clearly shown in Figure 1 lit to the surfaces of two sides of the post. They are united to the girths by fastening bolts 9 passing through apertures therein. The plate serves to reinforce the structure and adequately holds the girths 2 with the assistance of the angle iron in position.

Having thus described my invention, what I claim is:

The combination with a derrick having a rectangular corner post, of a pair of independent angle members, the vertical-flange of each member being secured to said corner post along one side thereof with said flanges occupying the same horizontal plane when attached to the corner post, girths resting on and supported by the horizontal extensions of said members, and a brace formed of a continuous piece of relatively flat metal and of angle shaped formation overlying both of said members, and fastening devices passing through said girths, the horizontal flanges of said members and said brace.

In testimony whereof I affix my signature.

CLARK a. RANNEY.
